netcore-boilerplate

Boilerplate of API in .NET Core 3.1 .NET 8

GitHub	Codecov

Boilerplate is a piece of code that helps you to quickly kick-off a project or start writing your source code. It is kind of a template - instead of starting an empty project and adding the same snippets each time, you can use the boilerplate that already contains such code.

Intention - The intention behind this project is to mix a variety of different approaches to show different available paths. That's why you can find here the Service approach mixed-up with Repository approach, or old-fashioned controllers mixed-up with brand new minimal API in a separate module (modular approach). As well as, it's a kind of playground for exploring frameworks, packages, tooling. At the end, You are in charge, so it's your decision to which path you would like to follow.

  • FeatureManagement
  • HealthChecks
    • MySQL
    • MsSQL
• Filters
  • Simple ApiKey Authorization filter - ApiKeyAuthorizationFilter.cs
  • Action filter to validate ModelState - ValidateModelStateFilter.cs
  • Global exception filter - HttpGlobalExceptionFilter.cs
• Configurations
  • Serilog configuration place - SerilogConfigurator.cs
  • Swagger registration place - SwaggerRegistration.cs
• Simple exemplary API controllers - EmployeesController.cs, CarsController.cs

  • Fixture with TestServer - TestServerClientFixture.cs
  • Very simple data feeder - BooksDataFeeder.cs
• Exemplary tests - BooksTests.cs

How to adapt to your project

Generally it is totally up to you! But in case you do not have any plan, You can follow below simple steps:

1. Download/clone/fork repository :arrow_heading_down:
2. Remove components and/or classes that you do not need to :fire:
3. Rename files (e.g. sln, csproj, ruleset), folders, namespaces etc :memo:
4. Appreciate the work :star:

Build the solution

Just execute dotnet build in the root directory, it takes HappyCode.NetCoreBoilerplate.sln and build everything.

Start the application

When running on Linux (i.e. WSL), make sure that all docker files (dockerfile, docker-compose and all mssql files) have line endings LF.

Just run docker-compose up command in the root directory. After successful build and start of all services visit http://localhost:5000/swagger/. To check that API has connection to both MySQL and MsSQL databases visit http://localhost:5000/health/.

Migrations

When the entire environment is up and running, you can additionally run a migration tool to add some new schema objects into MsSQL DB. To do that, go to src/HappyCode.NetCoreBoilerplate.Db directory and execute dotnet run command.

Run unit tests

Run dotnet test command in the root directory, it will look for test projects in HappyCode.NetCoreBoilerplate.sln and run them.

To Do
